Don't know if this has been mentioned; but, Handmade Electronics has the Solens and PC mount tube sockets for US builds.  Price was right too.

I know.. stupid question.. But it might also help some other people.
How do i connect the edcor IO trafo's?
The + - ground for the balanced side is simple, but what about the non balanced side? (so the compressor side)
Should i connect pin1 (+) to the postive and pin2 (CT) to ground or should i connect pin1 (+) to positive and pin4 (-) to ground?

hey guys,

On what secondary windings do I need center taps for the power transformer?

2 X 115V Primaries.

Secondaries:
220V 0.1A
9V 2.5A
24V 0.5A
Tube limiters..yum!

no center taps needed here, just:

220V 0.1A
9V 2.5A
24V 0.5A (optional, just for the relays etc, and can be different voltage)

for the D-AOC itself you only need the Heater and High Voltage, that's right.

you can use any zener in the range of 60V to 70V I would say, and they don't have to be 5W.

Hi,
my engraved front panel arrived.











Big thanks to Rowan, Volker, Darius, Jens and Frank. Sorry for the oversized picture, I thought I already reduced them, but somehow twin-x behaves unpredictable.
regards
Bernd

Very nice build!  Probably one of the more compact builds we'll see. :grin:   I hope to finish mine in just a week or two.  I just need tubes, knobs, 24V regulator, 2k trimpot, and my front panel.

Would an Ampex 4580200-01 transformer work on input on this.  It's supposed to be 10K:10K, and I have a couple laying around.  Does anyone know if these are any good for this application, or if they are decent for anything?  I saw CJ's evaluation; but, if anyone has any experience with them, I would be grateful to know about it.   I can't find much on the web about them.

Thanks,

Steve

I've got a couple of these as well and I'm planning on trying them...
